VALVE roR FLUSI-IING-TANKS.

Application filed December 16, 1913.

To all whom it may concern:

Be it known that I, ERNEST F ERRAN, a citizen of the United States, and a resident of the city and county of San Francisco and State of California, have invented a new and useful Improvement in Valves for Flushing-Tanks, of which the following is a specification.

My invention relates to improved valves for flushing tanks wherein a discharge valve is raised by a lever and retained on a stop by means of a float operated latch until the tank is nearly empty when it is automatically released by the said float operated latch and allowed to close, and the objects of my invention are first, to provide improved means for retaining the discharge valve in an open position that be simple in construction and inexpensive; second, to provide improved means for preventing leakage through the valve operating means. I accomplish these several features by means of the device disclosed in the drawings forming a part of the present specification, wherein like characters of reference designate similar parts throughout the said specification and drawings and in which- Figure 1 is a vertical sectional view ofa flushing tank, disclosing the valve attached thereto, the several parts being illustrated in a closed position. Fig. 2 is a broken sectional view disclosing the manner inwhich the valve is raised or opened and secured in such position until the tank is emptied. Fig. 3 is a vertical sectional view similar to Fig. 1 but disclosing a modified form wherein a valve is used to prevent leakage of the water through the valve operating means, the valve being shown closed.- Fig. 1 is a View similar to Fig. 3 but disclosing the valve in an open position.

Referring to the drawings, the numeral 1 is used to designate an air tight flushing tank having a cover 2 provided with a suitable gasket 3. The tank is lined with a suitable lining 4 and is also provided with a supply pipe 5. The water is discharged from the tank 1 through the discharge pipe 6 having a seat 7 adapted to receive a conical valve 8, recessed as at 8, and having an annular flange 9 at the top thereof. Vertical lugs 10 are provided at the top of the discharge pipe6 for the purpose of guiding the valve 8 to its seat 7. One of the lugs 10 is provided with a seat 12 which is adapted to engage the annular flange 9 and to sup- Spec'ification of Letters Patent.

port one side of the valve 8 in a manner hereinafter more fully described.

A latch 14-, having a seat 15, is pivotally secured to one side of the discharge pipe 6 as at 16 and has a rod 17 to the outer end of which is secured a float 18. The discharge pipe 6 extends below the tank 1 and has secured to the lower end thereof, an elbow 20 provided with a stufling gland 21. The elbow 20 is also provided with an arm 22 to which is pivotally secured the operating lever 23 having an extension 24 with a slot 25 in the end thereof. An operating rod 26 has its lower end pivotally secured within the slot 25 and after extending upward through the stuffing gland 21 and a tubular extension 27, engages the under side of the valve 8 within'the recess 8 thereof. A suitable pipe 30 issecured to the elbow 20 for the purpose of conveying the water from the discharge pipe 6 to the required spot.

The operation is as follows: The tank 1 having been filled with water under pressure from the supply pipe 5 until the air pressure above the water in the tank 1 is equal to the water pressure, the tendency of the float 18 to rise therein will cause the latch 14 to be normally pressed against the flange 9 of the valve 8. By pressing downward on the operating lever 23, the rod 26 rises through the extension 27 and raises the valve 8 from its seat until the under the float 18 will drop and remove'the latch 1 1- from under the flange 9 and allowthe same to slide from the seat 12 of the lug 10 and the valve 8 will drop to its seat 7 within the discharge pipe 6. The tank will then be again filled from the supply pipe 5, and the valve is ready for the next operation.

It has been found from experience that the stufling glands leak after having been in use for sometime. I have provided means for preventing this leakage by providing an extension 27 for the operating rod 26, the said extension extending into the recess 8' of the valve 8 so as to be above the flow of water from the tank 1. The flow of water through the discharge pipe 6 will act in much the same manner as an injector and cause a suction rather than a pressure at the upper end of the extension 27 and thereby prevent the flow or leakage of water through the valve operating means.

I have illustrated a modified form of the invention in Figs. 8 and 4 wherein the extension 27 is eliminated and the rod 26 is provided with a valve 31 which rests within the seat 3:2 when the said operating rods is in its lower position. Any pressure of water on the rod or valve will tend to seat the said valve 31 more firmly to its seat 32 and thus prevent leakage through the operating means.

It is obvious from the foregoing that I have provided a valve for flushing tanks that is cheap and simple of operation as well as construction, also one which will not leak. It is also evident that I have provided simple and effective means for retaining the valve in an open position while the water is being discharged from the tank, the same means being also adapted to release the valve when the tank is nearly emptied.

I am aware that the present state of the art discloses various devices for retaining the valve of a flushing tank in an open position wherein somewhat complicated means are employed for the retention of the valve which require alinement and numerous parts which not only render the construction eX- pensive but require frequent repairing and setting. Therefore, I do not wish to claim as my invention the broad idea of valves for flushing tanks, but

What I do claim as my invention and desire to secure by Letters Patent is- 1. In apparatus of the class described, the combination with a valve seat, of vertical lugs upstanding from said seat, one of the lugs having a shoulder near the upper end thereof, a valve for cooperating with said seat and having an annular flange, means for lifting said valve, and a float operated latch pivoted at its lower end and having a shoulder near its upper end, the said latch being arranged to normally thrust against the side of the flange and to move the shoulder on the latch underneath said flange and to move the flange onto the seat on the lugs when the valve is raised.

2. In a valve for flushing tanks, the combination of a conical seat and vertical lugs on the top thereof, one of the lugs'having a seat near the upper end thereof; a valve having an annular flange at the top and arranged to engage said valve seat; means for lifting the valve; and a float operated latch having a seat thereon, the said latch being arranged to normally press against the side of the flange on the valve when the same is seated and to move the seat on the said latch under the said flange and to move the flange onto the seat on the lug when the said valve is raised.

3. T he combination with a flushing tank of a discharge valve having a conical seat therein and vertical lugs arranged around the seat, one of the lugs having a seat; a conical valve having an annular flange near the top; a rod slidably mounted and arranged to contact with the conical valve; means for operating the rod and lifting the valve from its seat; a latch pivotally secured to the side of the discharge pipe and having a seat thereon adapted to engage the annular flange of the valve; a rod secured to the latch and having a float on the outer end thereof, said float being adapted to be raised by water within the tank and press the latch against the side of the flange on the conical valve when the valve is seated and to cause the seat on the latch to engage the valve and move the flange thereof onto the seat on the lug and support the valve when the same is raised and to release the said valve when the level of the water in the tank falls below the top of the discharge pipe.

4. The combination with a flushing tank of a discharge valve having a conical seat and vertical lugs near the top thereof, one of the lugs having a seat thereon; a conical valve having an annular flange thereon and adapted to engage the seat within the di charge pipe; an upwardly extending slidably mounted red, the upper end of the said rod resting against the bottom of the conical valve; means for raising the valve and the rod; a latch having a seat and pivotally secured at one side of the discharge valve; a rod secured to the latch and having a float on the outer end thereof, the said float bein adapted to press the latch against the side or the annular flange when the valve is seated and to cause the valve to be engaged by the seat on one of the lugs when. the said valve is raised and to release the said latch and allow the valve to drop when the water in the tank has been discharged.

In witness whereof I hereunto set my signature in the presence of two subscribing witnesses.
